------- Comment #7 from rguenth at gcc dot gnu dot org 2008-11-07 18:43 ------- During update_alias_info we collect the variables that are written to, but because we use gimple_stored_syms to get at them we miss those that are in memory partitions. If the new partitioning moves them out of a partition we then miss conflicts for them. Oops.
I have a patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38051
